VFD just stopped working Jaguar CUB 5A-1

[Ian PParticipant @ianp]

Fitted it to linisher with 1/2 HP motor a couple of weeks ago and was working fine until today. Display looks normal but motor does not rotate, no error message, checked all programmed parameters and wiring and all seems fine. Reverted to keypad operation (disconnected pendant) and still not a squeak.

If there is an electronic fault I would have expected an error code, does anyone have any similar problems with the CUB

The Jaguar cub is quite a neat and compact VFD let down a bit by documentation. I have the manual but its more confusing than the supposedly bad HuanYang one!

Not related to this problem but this is the first VFD I have seen with no settings for motor parameters, when I connected it up it just worked.

There should be a code to reset the VFD to its default settings.

We used to fit a lot of Jaguar cub inverters. The little blue ones. The docs are quite complicated. It was a long time ago when we used those, but always very reliable in operation. I still have a couple of the 3ph in 3ph out ones somewhere, Hope you get it sorted as they were an expensive good quality unit.

'Docs quite complicated' I can cope with that. The difficult bit with this manual is trying to get inside the head of whoever wrote it.

The parameters are sensibly numbered as F01, F02, F03 etc and each one has a little paragraph, after the last one it then changes (in the manual) to E01, E02, E03 etc then C01, C02, C03, followed by a solitary 'P00'. Then the prefix is an H (up to H25) followed by some 'e' prefixed settings. Unfortunately whilst how to get into the F parameters is shown, I cannot find how the E, C,and H numbers are accessed.

Prefix letter are explained as, F is Fundamental function, E is Extension Terminal function, C is Control functions of frequency!, H is High Performance. The P0 is motor Parameter (this can be set between 0 and 9 but no explanation of what is is!)

I was hoping someone may have experience of this VFD and may be able to throw some light on its operation

From vague distant memory, there was a setting that had to be altered & then with that done you could access all the hidden menu's if that makes sense. It was like you had to change a value from 0 to 1 then it opened up the other parameter selections. Sorry not to be much help. Have you tried to get any help from Jaguar. They must have a help desk, assuming they are still trading. Or even youtube.

Hi Ian, I have just downloaded the manual. I think the function I mentioned was F00 set to 0 lets function code data be edited.
